The purpose of this study was to determine the attitudes of teenagers toward the First Amendment, to compare the attitudes of Florida teenagers with those of non-Florida teenagers, and to compare the attitudes of journalism students with teenagers not in journalism classes. A total of 430 students from Florida high schools and 457 from high schools in other states completed a four-page questionnaire dealing with freedom of the press, criminal trial reporting, obscene words, derogatory statements, misleading advertisements, news of riots and demonstrations, and propaganda about communism. Conclusions from the study indicated that (1) teenagers have no precise understanding of the First Amendment in relation to press freedom, (2) they approve rigid controls incompatible with the First Amendment, (3) journalism students have no better understanding of freedom of the press than do non-journalism majors, (4) journalism instruction either de-emphasizes press freedom or is ineffectual in its attempts to interest teenagers, (5) teenagers in Florida resemble students in other states in their attitudes, and (6) teenager attitudes probably reflect the values and attitudes held by parents and teachers.
